Clean Snowmobiles: P2 in Action
Cleaner Snowmobile Technology P2 Options Reducing Snowmobile Pollution: 

What snowmobile dealers, tour operators, fleet managers, and snowmobilers can do TODAY to reduce the pollution from snowmobile fleets and personal snowmobiles.**

  • Adjust the snowmobiles for local conditions and altitudes, including:
    • Use the proper jet size for the elevation. Carburetor jets with smaller orifices should be used at higher elevations. Use of the smaller jets results in more complete fuel combustion.
    • Adjust Clutches. Installation of proper jets for higher elevation also improves engine performance, and snowmobile clutches should be adjusted to match performance.
    • Keep the engine tuned properly.
  • Use oxygenated fuels, such as 10 percent ethanol blend, in the snowmobile to reduce emissions.
  • Use synthetic low-particulate lube oils to reduce particulates and smoke.
  • Use synthetic biodegradable lube oils to reduce potential impacts to health and the environment.

What you can do to reduce snowmobile emissions even more… support the development of cleaner snowmobile technology and sell, purchase or rent cleaner machines as they become available to the public.

Cleaner Options:

Snowmobile manufacturers are introducing cleaner, four-stroke snowmobiles to the marketplace. Selling, purchasing and/or renting these snowmobiles, creating a market for cleaner machines, is the most important thing you can do to reduce the impact of snowmobiles on the environment.

The SAE Clean Snowmobile Challenge is a student design competition formed to encourage the development of cleaner and quieter snowmobile technology while simultaneously providing a hands-on educational experience to college students. This program works find new methods to prevent pollution from snowmobiles (http://www.sae.org/students/snow.htm).
